<p><em><strong>By Dr. Ahmad Naeem </strong></em></p>



<p>The creation of the universe is a fascinating and complex story. It takes curious minds on an endless journey of wonder. But along with that, the story of how elements and compounds—like water—came into existence is just as amazing.</p>

<p>About <strong>13.8 billion years ago</strong>, the universe began from an incredibly small, hot, and dense point. Then, with a massive expansion called the <strong>Big Bang</strong>, everything—time, space, matter, and energy—was born.</p>



<p>This wasn’t an ordinary explosion. It was the rapid spreading of space itself. As energy spread out, it began turning into matter. In just seconds, the universe grew faster than the speed of light. As it expanded, it cooled down, allowing particles like <strong>quarks</strong> and <strong>electrons</strong> to form.</p>



<h3 class="wp-block-heading" id="h-the-birth-of-atoms"><strong>The Birth of Atoms</strong></h3>



<p>Within minutes, these tiny particles combined to make <strong>protons</strong> and <strong>neutrons</strong>. Then, the first and simplest element was formed: <strong>hydrogen</strong>. A small amount of <strong>helium</strong> was also created. These were the universe’s first building blocks.</p>



<p>But the universe was still <strong>dark</strong> for hundreds of thousands of years. Light couldn’t travel freely because everything was packed in a hot, dense state.</p>



<h3 class="wp-block-heading" id="h-when-light-broke-through"><strong>When Light Broke Through</strong></h3>



<p>Around <strong>380,000 years</strong> after the Big Bang, things cooled down enough for electrons to join with protons to make stable atoms. That’s when light was finally able to travel freely across space. We still detect this first light today. It’s called the <strong>Cosmic Microwave Background</strong>—a soft echo of the Big Bang.</p>

<p>Even then, stars hadn’t formed yet. The universe was filled with giant clouds of hydrogen and helium gas.</p>



<h3 class="wp-block-heading" id="h-the-first-stars-lighting-up-the-universe"><strong>The First Stars – Lighting Up the Universe</strong></h3>



<p>After <strong>100–200 million years</strong>, gravity pulled gas clouds together until they became hot and dense enough to ignite. The <strong>first stars</strong> were born. These were huge and different from today’s stars. They contained only hydrogen and helium—no heavy elements like oxygen or iron.</p>



<p>These stars, called <strong>Population III stars</strong>, lived short but powerful lives. They burned quickly and ended in huge explosions called <strong>supernovae</strong>.</p>



<h3 class="wp-block-heading" id="h-how-the-first-water-was-formed"><strong>How the First Water Was Formed</strong></h3>



<p>Inside these giant stars, nuclear fusion created heavier elements like <strong>oxygen</strong>. When the stars exploded as supernovae, they spread these elements into space.</p>



<p>Some very massive stars exploded in a special way called <strong>Pair-Instability Supernova</strong>. These explosions completely destroyed the stars and released huge amounts of oxygen into space.</p>



<p>This oxygen then joined with hydrogen in cold clouds called <strong>molecular clouds</strong>, forming the first <strong>water molecules</strong>.</p>



<h3 class="wp-block-heading" id="h-a-universe-full-of-water"><strong>A Universe Full of Water</strong></h3>



<p>Computer models show that these ancient clouds had <strong>10 to 30 times more water</strong> than today’s Milky Way clouds. That means water existed in large amounts when the universe was just 100–200 million years old.</p>



<p>Earlier, scientists thought water slowly increased over billions of years. But <strong>new research</strong> shows that the first stars filled the universe with water <strong>much earlier</strong> than we expected.</p>

<p>Later, these early elements, including water, became part of large clouds called <strong>nebulae</strong>. Gravity continued shaping them into new stars and planets.</p>



<p>Our <strong>solar system</strong> also formed from such a nebula, around <strong>4.6 billion years ago</strong>. Water was already present in that nebula and became part of the Earth. Some of it came through <strong>comets</strong> and <strong>asteroids</strong> during Earth’s formation.</p>

<p><strong>It’s amazing to think that the water we drink today may be older than Earth, the Sun, or even the Milky Way Galaxy. It was created when the first stars died and has traveled across space ever since.</strong></p>

Every drop of water might be older than our Sun and Galaxy!
